First of all, thank you for your excellent work. I understand this if V1 and V2 are connected to the ends of R1 and R2 . The fact that two instruments are connected at A and B, confuses me. What does that mean? If we don't touch the connections and simply move V1 next to V2, what value will we measure? Will the value on the instrument change? Could this mean that we also measured the value induced in the wires we used to connect the instruments? Even in this case, your statement still holds. Thank you. I wish you all the best
if we swing V1 over to the same side as V2 without cutting any cables then they will both show the same voltage. I suggest you also watch this video th-cam.com/video/wz_GqO-Urk4/w-d-xo.html
Anyone 2024-25
It only need courage, dedication and discipline to pass any exam ... Thank you sir 😊
All the best
Hi sir I am a JEE aspirant from India. Love your videos sir❤
Found you recently,and I can proudly say that I'm addicted to your videos .Keep it up Sir :)
Tis picture is a horror. It seems harmless, jewish people went by train, at the beginning some thought, they will go to a work place. Really, they didn't know what attended to them. This Germans were brutes and very dangerous. That was a result of education, not of human nature.
*99% of the Germans loved Hitler and all read Mein Kampf; they all Knew what was happening. After the war they all said "Wir habe es Nicht Gewust" *but all were all GUILTY like HELL*
Nazi Camps | Holocaust Encyclopedia *Nazi Germany and its allies established over 44000 concentration camps and incarceration sites during the Holocaust* and yet almost all Germans after the war said *Wir habe es nicht gewusst*
Fear for SS and Gestapo was not yet there in 1933-36 when Hitler was considered a gift of god by 99% of the Germans. Yet they could all read Mein Kampf and thus they all knew what would happen. 6 million jews were slaughgtered to death among them half my family.
This is of course one of the greatest lectures from a great professor. Thank you very much prof. Walter Lewin ❤❤❤❤❤
Thank you, that is very kind of you to say.
Dear Dr. Walter Lewin, I am a Master's student in the Faculty of Physics, and this is largely thanks to you. You are the first person I ever saw who loves physics so deeply and sincerely. You inspire me immensely, it’s amazing to see someone so dedicated to their passion. I can't even count how many times I've rewatched your lectures and other videos-they always lift my spirits. You know, when studying became exhausting and I questioned why I was doing all of this, why I chose to study physics, I would think of you. I’d reread your book, and every time, I’d remember just how much I love physics and how much I want, like you, to share this love and inspire others. Thank you so much! Thank you for your support, your work, and your inspiration! You are incredible person and outstanding lecturer!
thank you Anastaslia for your wonderful msg. You made my day ❤️
Nice video sir
Thank you!
Any jee aspirant here😅
This is a fresco of "The Massacre of the Innocents" painted by Giotto in the early 14th century (around 1305).
Thank you sır ı love ♥️

Sort of like the news they say what they want to share and censored the rest that doesn’t complement what they’re trying to portray, but if you have a picture or video of what actually happened, it gives the reader more clear interpretation of what was going on during that time rather than going by hear say!
If the signed hard back copy is still available I would like a signed copy with a picture if you can Dr Lewin
hard back copies are very rare. I only have 3 left. I am willing to sell 1 for $200 + postage. I will write a message for you in the book and will also add a signed copy of my picture. A hard copy is heavy. Postage to Europe could be $25 postage to India even more.
Giotto was important because he made paintings look more realistic by adding depth and emotion. He focused on making people and scenes look natural, which was a big change from the flat, stylized art before him. His work helped inspire the Renaissance and influenced other artists to make their art more lifelike. I think he was trying to express what was actually occurring during that era rather then just going by what was told in the literature that we have of that time!
listen again more carefully what I said about the key change he made.
@ he created the illusion of space!!
He introduced realism to art, he gave his figures weight, depth, and natural expressions, making them look three-dimensional and emotionally human, shifted his paintings feel more lifelike and relatable.
@@EZEMPIRE_LABORLINKED that is what the renaissance was all about. Giotto was the father of the renaissance - Proto Renaissance 1200-1400, Renaissance 1400 - 1600
@ thank you this gives a beautiful new perspective
Hello jii
I dont know about it Sir.I genuinely Agree❤.My favourite subject was Science from Childhood.Anyways Love you Sir ❤.
Artist: Giotto Subject: Massacre of the Innocents Period: Italian Renaissance painting Created: 1304-1305 Matthew tells the story of the Massacre of the Innocents. King Herod ordered the killing of all boys under the age of two born in the Bethlehem area, for the Magi had told him that a child destined to become the king of the Jews had been born in the city. Jesus was saved from the massacre when his Family fled to Egypt.
excellent - however this was made before the Italian Renaissance - it's called the Proto Renaissance (1200-1400).
Alright sir he was a printer and architect but what kind of uniqueness and beauty he had depicted in his art he had made at Chapel I mean what he wanted to convey although i like european art whenever study history. Is his art was influenced by Religion.
By the way i predict that you are reading commemts and will read for more time now as its a best way to communicate with people in retirement days even though you are not retired.
❤❤❤
it’s Giotto. The massacre of innocents in Assisi Italy! Wonderful church, i live 30 minutes from there
wow only 30 minutes - you must have seen it often
First see and first like
Nice ❤
I wish I can experience this live. Watching from Nigeria
Sir why someone use money to push 2.88? Are you alright
This topic will be on my exam next week! Thank you for the mini lecture it was very helpful.
Hello Professor! I was having a hard time understanding how lenz law works with an RL circuit, but after watching this video, I understand it so much more! Thank you for posting these wonderful lectures online for free.
Hmmmm.... is this where Billy Gaede got his Rope Model idea from? Cause I am telling you right now Prof. Lewin! IT'S NOT MAGNETS ALL THE WAY DOWN! IT'S YOYOS, CAROSELS AND ROPES!
I am doing bsc in physics major in India, and 50% students in my class have got admission in class due to their caste, and I was struggling to get admission in college due to this reservation system even I have scored way higher than those in my 12th exams.
Walter, why do you love physics? why should one study physics?
I was born for Physics and Physics was made for me
Oh, how I wish I could have been your student in person. Thanks for making all of this public and free.
you are very welcome
Coo, but come on. this is highschol level Newtonian inro physics.
very true
A visual lecture with good explanation. Thank you professor Walter Lewin
You are very welcome
When school was school. Not today's crap
Hello, sir. I hope you are doing well. Kindly say how others may perceive us the one we see through back camera/ front camera or mirror. Thankyou
I can't help you with that.
No problem
Best
Jeeeee and neeet exam
How old are you honorable teacher
stone age
I
My teacher sent this
@LecturesbyWalterlewin Does sir has channel or something where he can share academic resources, Physics research papers and insights..?
no that does not exist on my channel
It's painful we can hear pain in his voice😢
Jai hind sir ❤
It isn’t physics… it’s gravity.
???
Excuse me. A child knows this just by swinging.
Prof. E^2 = m^2 * c^4 + p^2 * c^2 * [n(E - Ep)^n]
Einstein's Theory of SR: E^2 = m^2 * c^4 + p^2 * c^2
@@lecturesbywalterlewin.they9259 Hi Prof. I know you think I made a mistake with my formula but what I wrote is based on my SUFT formula and the new discoveries it. That stands for Super Unified Field Theory that's why it's different than Einstein's. Let me explain a little bit to you and it'll make more sense. The reason nobody has been able to do a Unified Field Theory is for one very big reason. The first thing They needed to do is Quantize Time and that turned out to be the Most Important piece in the Whole formula. Without that it just plain Can't be done and No way to Unify Quantum Mechanics and Relativity at least not properly!! Once that was done All the other pieces starting to fall into place like muons that have a life of a few seconds become stable. What started the quest for that turned out to be the original riddle regarding the speed of light. Why was it a riddle what happens to everything that gets close to the speed of light it slows down or stops which means light would also be affected. Unless something was altering that situation. It turned out to be Time because is not a light barrier it's that Time barrier for lack of a better term. The reason why Einstein's E= mc2 turned out to be another surprise, a major one and that was there is a timestamp on light. That's why his formula still worked. So the two are actually in a relationship that happened at the Big Bang and has been going on ever since. There was all kinds of surprises but like a large puzzle with no picture on the pieces they All still started to fall into place. I have sent e-mails to the people CERN, The Perimeter Institute, MIT And Multiple Other Universities trying to get it peer reviewed and feedback. I want to see if somebody can actually find flaws in this formula and I mean I want them to try and tear it apart and scrutinize it. Simply put if it's as strong as I know that it is it will stand up to anyone's rigorous examination and passed with flying colors. You did tell me to get it published in nature It needs to be peer reviewed first or they won't touch it and I don't blame them one bit so that's what I'm working on. Like you told me too many people have walked up to you and said I have this or I have that and it turned out to be Junk or Flawed or Both. Simply put I have no intentions of wasting anyone's time and I definitely am not going to waste my own either. I have other projects, I could have spent the time on. So right now I'm waiting to hear back from these different people and see what they say! I posted that for you cause I thought you might be curious to what I've been up to not to bug you. I will post you a comment when I hear back from any of them to let you know what they said if I am wasting their time or my own. I've heard people say that if a unified field theory is found, it would Wreck Physics. I believe it will just opened new doors for new discoveries and re-energize science. it will make it so scientist while proper data so they can make real discoveries in a major way. Don't get me wrong there are things in my formula about are hypothetical but they are testable and provable is far as I understand where science is right now. Thank you for getting back to me. John
@@01timegone *I have sent e-mails to the people CERN, The Perimeter Institute, MIT And Multiple Other Universities trying to get it peer reviewed and feedback* Noone will respond to you. Trust me I was 43 on the MIT Physics faculty. We receive similar nonsense several times per year. But we never respond to it. I suggest you also read this nonsense www.vanocken.com/
Van Ocken also calls his nonsense the Theory of Everything. Against my advice he even sent an article to Nature. Ofcoz they rejected it as nonsense will never be published in a refereed journal. *If you send you theory to Nature, the same will happen.* Try it!!!!
the famous Physicist Pauli who received the Nobel Prize is also known for his statement when he read some totally absurd Physics. He would then say *"this is not even wrong" Your Theory is NOT EVEN WRONG*
